This invention relates to an improvement in louver ventilators for use in connection with doors, transoms, windows, etc.

. Referring to Figure l of the drawing, the

present invention is shown mounted for use in a door 10. The usual panels 11 are fitted between the door stiles 12 and above the uppermost panel rails 14 and 15 are provided, between which a ventilator opening is created. The ventilator 17 is mounted in the opening thus provided,being securely held in place; in any desired manner, preferably, however, ashereinafter described. 1

The ventilator is comprised of channeled stiles 19, the open faces of'which are pror jected in opposite directions and adapted to form,-with the door stiles 12, closed vertical pockets 20. For the purpose of description, the ventilator 17 is considered as having inner and outer faces 21 and 22, the movable .i. and fixed louvers being on the inner and outer faces respectively. To complete th-e rectangular frame of the ventilator, a top rail 24 is provided, being secured in any desired manner to the stiles 19. Adjacent the inner face i i 21 of the ventilator, the rail 24 is formed with a downwardly and inwardly projecting flange 25. Adj acentth-e outer face 22 of the ventilator, the rail 24 is bent downwardly, outwardly and upwardly to form flanges 26,27 and 28respectively. By reason of the flanges 25 and 26, a partially closed pocket 30 is created, the purpose of which will be more clearly understood from a further description of the invention. J oined'to the flanges 32 of the stiles 19 in any suitable manner, asby rivets 33, are'angular elements 35. The elements 35 follow the contour of the stiles to the approximate center of the inner wall 36, whence they project inwardly toform' supporting flanges 38. a 7 Y The fixed louver-s 39Yare formed with a generally curved portion 40 terminated along one'edge by a flange 41. The ends of the flanges 41 are welded or otherwise'suitably joined to the flanges 38 of the elements 35 (see Figure '6); Should the ventilator 17 be of considerable length, it is deemed necessary to provide a central supporting strip 43 to which the flanges41 of the fixed louvers 39 r are welded or otherwise secured. The flanges 38 of the elements 35, at their upper ends, approach the flange 26 of the rail 24, produc ing small pockets within the pockets 30. Intothese small pockets the ends of the upper louver 39 are projected. A channel plate 44 is mounted on the portion of the rail 24 defined by flanges 26, 27 and 28, being secured by rivets 45 to'the flange 28. Thisplate'provides a rail finish similar in contour to the lower rail, hereinafter to be described.

The vertical flange 53 of thiselement is spa-cedfrom the flange 38 by a felt or other silencing material 55. Rivets 56 join the elements 46 and 4%? together through the felt and at the ends of the ventilator through the flanges 38. The upper edge of the element 47 terminates in an outwardly extending flange 58 which constitutes a stop orv limit to the movement of the ventilator from z opened to closed position. 5

The movable louvers 59, being similar-to the fixed louvers 39, are formed with curved portions 60and upstanding flanges 61. These louvers are formed with blank ends which are curved to form hollow pins 63, the purpose of which is to provide pivotal support therefore. Adjacent the flanges 38, the walls 36 of each of the stiles 19 are provided with a number of uniformly spaced, vertically v alingedopenings 64:, the openings corresponding to the number of movable louvers. The pins 63 project through the openings 64 and extend well intothe closed pockets 20. It is pointed out that the bearing support for the ends of'the movable louvers 59, being produced directly from the louvers themselves, greatly reduces the manufacturing and installation costs. Within one of the closed pockets 20 :is located a longitudinally extending rod 66 having spaced openings therein corresponding to the number of movable louvers. Mounted on each of the pins 63, and secured thereto against rotation, are links 67 having ends 68 a formed with openings corresponding in size with the openings in the rod 66. Rivets 69 pivotally connect the links to the plate. It is obvious that by opening or closing one of the louvers, the other movable louvers, being connected to the operated louver through rod 66 and links67, will open or close together.

It will be noted that the movablelouvers 59 are so arranged that'the curved portion 60 of the'upper louver overhangs the flange 61 of the louver mounted therebeneath when the ventilator is opened as shown in Figure 45., When the louvers are moved to closed position (see Figure 5) the flanges 61 move outwardly and the curved portion 60 moves inwardly. Consequently, opposite portions of 71. The present embodiment of the invention discloses a ventilator fitted in the upper part of a door at which height it is easily operated by the handle 70. If, however, the ventilator is mounted above the door, in a transom for example, or in the upper part of a window opening, suitable; linkages areprovided by which to actuate the operating handle 70.

The device, as described, comprisesa com; plete unit which is mounted in the opening provided therefore. When so mounted, screws 73 secure the ventilator to the lower and upper rails 14: and 15 of the door. Suitable moulding/74 may be added to effect a finished installation.

Although applicant has disclosed but one modification 'of his invention and only one application of use thereof, it is'not intended that he be limited thereto, since it is obvious to those skilled inthe art that othermodifications or applications of the device maybe made without departing from the spirit and scope of the invention as defined by the here-- unto annexed claims. K V

:Having thus set forth my invention What I claim as new and for whichl desire protection byLetters Patent is: 1. A ventilator unit ofthe class described comprising stiles, oppositely disposed fixed and movablelouvers mounted between vsaid stiles, axial pins formed integral jwith the ends of said movable'louvers and projecting through said stiles, links fixed to said pins, and a 'plateconnecting' said links whereby manipulation of one louver causes all of said movable louvers to beactuated. x

'2. In a ventilatorunit of the class described, a'set of fixed louvers,-outwardly and downwardly curved portions projecting below-the upper edge of the louver therebeneath, a set of similarly formed reverselydisposed. movable louvers, saidmovable louvers being arranged in thesamehorizontal plane with said fixed louvers, and means pivotally supporting said movable louvers, said means being adapted to permit actuation of said movable louvers without permitting the passage of light from one side of the ventilator unit to the other. 3. A ventilatorunit comprising'stiles,ioppositely disposed fixed and movable louvers mounted between said stiles, co-axial pins formed integral with the ends of said movable louvers and projecting into said stiles, said pins being located centrally of the edges of said movable louversso that adjacent edges ofsaidmovable louvers mayoverlap and contact'wi'th'each'other whereby to' prevent the passage of air through said ventilator;

- 4. A ventilatorunit comprising stile-s, oppositely disposed fixed and movable louvers mounted between said stiles, co-axial pins formed integral with the ends of said movable louvers, and projecting-into said'stiles, said pins being located substantially centrally of the edges'of said movable louvers to provide a pivotal support therefor, links secured to the ends of said pins and a plate connecting all of said links, said plate being adapted to synchronize the movement of all of said movable louvers whereby adjacent edges thereof Will contact With each other to prevent the passage of air through said ventilator.

5. A ventilator unit comprising stiles, oppositely disposed fixed and movable louvers mounted between said stiles, co-axial pins formed integral with and projecting beyond the ends of said movable louvers, said pins being located substantially centrally of the edges of said louvers and provide a pivotal support therefor, links joined to said pins and concealed in said stiles, said links being connected to each other so that movement of any one of said louvers causes simultaneous movement of all of said movable louvers.

In testimony whereof I have afliXed my signature.
